Inflammatory markers in world trade center workers with asthma: Associations with post traumatic stress disorder.

BACKGROUND: Post-traumatic stress disorders (PTSD) is associated with worse asthma outcomes in individuals exposed to the World Trade Center (WTC) site. RESEARCH QUESTION: Do WTC workers with coexisting PTSD and asthma have a specific inflammatory pattern that underlies the relationship with increased asthma morbidity? STUDY DESIGN AND METHODS: We collected data on a cohort of WTC workers with asthma recruited from the WTC Health Program. Diagnosis of PTSD was ascertained with a Structured Clinical Interview for DSM-5 (Diagnostic and Statistical Manuel of Mental Disorders) and the severity of PTSD symptoms was assessed with the PTSD Checklist 5. We obtained blood and sputum samples to measure cytokines levels in study participants. RESULTS: Of the 232 WTC workers with diagnosis of asthma in the study, 75 (32%) had PTSD. PTSD was significantly associated with worse asthma control (p = 0.002) and increased resource utilization (p = 0.0002). There was no significant association (p>0.05) between most blood or sputum cytokines with PTSD diagnosis or PCL-5 scores both in unadjusted and adjusted analyses. INTERPRETATION: Our results suggest that PTSD is not associated with blood and sputum inflammatory markers in WTC workers with asthma. These findings suggest that other mechanisms likely explain the association between PTSD and asthma control in WTC exposed individuals.

World Trade Center workers with asthma and post-traumatic stress disorder perceive airflow limitation more accurately.

BACKGROUND: Post-traumatic stress disorder (PTSD) is a major risk factor for increased asthma morbidity among World Trade Center (WTC) workers. OBJECTIVE: To investigate whether differences in perception of airflow limitation mediate the association of PTSD with worse asthma control in WTC workers. METHODS: We collected data from WTC workers on asthma control (Asthma Control Questionnaire and Asthma Quality of Life Questionnaire) and daily peak expiratory flow (PEF) measures over 6 weeks. Perception of airway limitation was assessed by comparing guessed vs actual PEF values. Post-traumatic stress disorder was diagnosed using the Structured Clinical Interview. We used unadjusted and adjusted models to compare PEF and perception measures in WTC workers with PTSD with those of workers without PTSD. RESULTS: Overall, 25% of 224 participants had PTSD. Post-traumatic stress disorder was associated with worse Asthma Control Questionnaire (2.2±0.8 vs 1.1±0.9, P < .001) and Asthma Quality of Life Questionnaire (3.9±1.1 vs 5.4±1.1, P < .001) scores. Adjusted analyses showed no significant differences in PEF between WTC workers with (351.9±143.3 L/min) and those without PTSD (364.6±131.6 L/min, P = .55). World Trade Center workers with PTSD vs those without PTSD had increased proportion of accurate perception (67.0±37.2% vs 53.5±38.1%, P = .01) and decreased underperception (23.3.0±32.1% vs 38.9±37.5%, P = .004) of airflow limitation during periods of limitation. Similar results were obtained in adjusted analyses. CONCLUSION: This study indicates that differences in perception of airflow limitation may mediate the relationship of PTSD and increased asthma symptoms, given WTC workers with PTSD have worse self-reported asthma control, an increased proportion of accurate perception, and decreased underperception, despite no differences in daily PEF measures.

Assessing the interrelationship between asthma and obesity self-management behaviors.

Asthma and obesity are common coexisting conditions with increasing prevalence and substantial morbidity. This study examines the inter-relationship between illness and treatment beliefs in asthma and obesity and how they influence self-management behaviors. Overweight and obese adults ≥ 18 years with asthma were recruited from primary care and pulmonary practices in New York, NY and Denver, CO (n = 219). Path analysis was used to examine the relationship between asthma, weight and exercise-related illness and medication beliefs and SMB. Necessity beliefs about asthma medications and diet were associated with better medication adherence and healthier dietary behaviors (ß = 0.276, p = < 0.001, ß = 0.148, p = 0.018 respectively) whereas concerns about these self-care activities were associated with poorer adherence and worse dietary behaviors (ß = - 0.282, p < 0.001, ß = - 0.188, p = 0.003 respectively). We found no statistically significant association of exercise behaviors with any other weight or asthma illness or treatment beliefs. Our study demonstrates that necessity and concerns about treatment are associated with adherence in asthma and obesity. The lack of association of exercise behaviors with any asthma or weight related beliefs may reflect limited awareness of the impact of weight on asthma and warrants additional research.

Feasibility Trial of a Comprehensive, Highly Patient-Centered COPD Self-Management Support Program.

Purpose: To test the feasibility of a novel self-management support intervention for people with chronic obstructive pulmonary disease (COPD). Methods: We conducted a feasibility randomized controlled trial involving patients ≥40 years with severe or very severe COPD in New York, New York (n=59). Community health workers screened patients and addressed barriers to COPD self-management. Patients were also offered home-based pulmonary rehabilitation (HBPR) and an antibiotic and steroid rescue pack. Control patients received general COPD education. Clinical outcomes for intervention and control were compared by difference-in-differences (DiD) at baseline and 6 months. The study was not powered for statistically significant differences for any measure. Feasibility measures were collected at 6 months. Results: There were high rates of completion of intervention activities, including 75% of patients undergoing evaluation for and participating in HBPR. Most (92%) intervention patients said the program was very or extremely helpful and 96% said they would participate again. Clinical outcomes generally favored the intervention: COPD assessment test, DiD -1.1 (95% confidence interval [CI] -5.9 to 3.6); 6-minute walk test distance, DiD 7.4 meters (95% CI -45.1 to 59.8); self-reported hospitalizations, DiD -9.8% (95% CI -42.3% to 22.8%); medication adherence, DiD 7.7% (-29.6%, 45.0%), and Physical Activity Adult Questionnaire, DiD 86 (95% CI -283 to 455). Intervention patients reported more emergency department visits, DiD 10.6% (95% CI 17.7% to 38.8%). Conclusions: A highly patient-centered, self-management support intervention for people with COPD was well received by patients and associated with potential improvements in clinical and self-management outcomes. A fully powered study of the intervention is warranted.

The relationships between Physical activity and asthma control and Body Mass Index (BMI) in patients with asthma.

OBJECTIVE: Asthma is one of the most common chronic conditions in developed countries. We examined whether physical activity (PA) is related to asthma control and body mass index (BMI) in asthma patients. METHODS: Cross-sectional data collected on PA (ActiGraph GT3X-BT), asthma control (the Asthma Control Questionnaire; ACQ), and BMI were examined in 206 adults (mean[sd] age 47.2[13.8] years; 49.5% had an obese BMI) with clinically diagnosed asthma. Relationships between PA and continuous BMI and asthma control were assessed using linear regression. Differences in PA across obesity (non-obese: <30 Kg/m2/obese: ≥30 Kg/m2) and asthma control categories (controlled: ≤0.75/uncontrolled: >0.75 ACQ score) were also examined. RESULTS: Median (p25, p75) steps counts and peak cadence were 6035 (4248, 8461) steps/day and 123 (115, 133) steps in a minute, respectively. There were nearly 2000 fewer steps/day among those with uncontrolled asthma versus controlled and among those with obese BMI versus nonobese, respectively (both p < 0.05). In regression models adjusted for relevant covariates each 1-unit increase in ACQ score was associated with -686 [95%CI -997, -13] (p ≤ 0.05) average steps/day. The statistical significance of these findings was attenuated (p ≥ 0.05) when BMI was added to the model. However, the point estimate was not reduced (-766 [95%CI -1060, 34]. CONCLUSIONS: Overall step counts were low in this population despite peak cadence values suggesting that most participants could perform moderate intensity activity. Increasing step counts should be considered an important lifestyle intervention goal in obese and non-obese asthma patients with low PA levels.

Delays in Diagnosis and Treatment of Bacterial Meningitis in NYC: Retrospective Cohort Analysis.

Community-acquired bacterial meningitis (CABM) morbidity and mortality remains high in those infected. Rapid diagnosis and treatment is paramount to reducing mortality and improving outcome. This retrospective cohort study aims to assess the time from presentation to diagnosis and treatment of vaccine preventable CABM as well as identify possible factors associated with delays in diagnosis and antibiotic administration. A retrospective chart review was conducted of individuals who presented to Columbia University Irving Medical Center (CUIMC), Children's Hospital of New York (CHONY), Mount Sinai Medical Center, and Weill Cornell Medical Center with BM due to Haemophilus influenzae type B, Streptococcus pneumoniae, and Neisseria meningitidis between January 1, 2012 and December 31, 2017. Diagnosis was delayed by more than 8 hours in 13 patients (36.1%) and 5 individuals (13.9%) had a delay of 4 hours or more from presentation to the administration of antibiotics with appropriate CNS coverage. All of these patients were also initially misdiagnosed at an outpatient clinic, outside hospital, or emergency department. This retrospective study identified febrile and/or viral infections not otherwise specified and otitis media as the most common misdiagnoses underlying delays from presentation to diagnosis and to antibiotic treatment in those with BM.

The Relationship Between Post-Traumatic Stress Disorder and Self-Management Behaviors in World Trade Center Workers with Asthma.

BACKGROUND: Comorbid posttraumatic stress disorder (PTSD) is highly prevalent and associated with increased morbidity among World Trade Center (WTC) rescue and recovery workers with asthma. However, the potential behavioral pathways underlying this relationship remain unclear. OBJECTIVE: To evaluate whether PTSD is associated with lower adherence to asthma self-management behaviors among WTC workers with asthma. METHODS: We used data from a prospective cohort of WTC workers with a physician diagnosis of asthma who were prescribed controller medications. Presence of comorbid PTSD was determined based on structured clinical interviews. Asthma self-management behaviors included medication adherence, inhaler technique, use of action plans, and trigger avoidance. We conducted unadjusted and multiple regression analyses to evaluate the association of PTSD with asthma self-management. RESULTS: Overall, 30% of 276 WTC workers with asthma had comorbid PTSD. Posttraumatic stress disorder was associated with worse asthma control and poorer quality of life. However, PTSD was not significantly associated with medication adherence (odds ratio [OR] -0.15; 95% confidence interval [CI] -0.5 to 0.2), inhaler technique (OR -0.12; 95% CI -0.7 to 0.5), use of action plans (OR 0.8; 95% CI 0.4 to 1.8), or trigger avoidance (OR 0.9; 95% CI 0.4 to 1.8). CONCLUSIONS: We did not find significant differences in key asthma self-management behaviors between WTC workers with and without PTSD. These results suggest that other mechanisms, such as differences in symptom perception or inflammatory pathways, may explain the association between PTSD and increased asthma morbidity.

Critical Analysis of a Challenging Case of Post-Infectious N-Methyl-D-Aspartate Receptor Encephalitis.

Infections are increasingly recognized as a common trigger of autoimmune disease, including autoimmune encephalitis. A significant association is particularly shown between HSV-1 encephalitis (HSVE) and a post-infectious autoimmune encephalitis mediated by neuronal autoantibodies, most notably anti-N-methyl-D-aspartate receptor (NMDAR) antibodies. The clinical significance of these and other novel post-infectious autoantibodies has led to new diagnostic and treatment challenges for clinicians. Here we present a case of a 19-year-old female with premorbid psychiatric disease and neuropsychiatric sequelae from HSVE who presented over a year after her initial HSVE with behavioral changes and positive anti-NMDAR antibodies. The clinical challenges encountered during this case are explored in detail based on a review of the literature. Research is needed to help guide management in these complex clinical situations.

Clinical and electrographic features of persistent seizures and status epilepticus associated with anti-NMDA receptor encephalitis (anti-NMDARE).

Based on a multicenter cohort of people with anti-NMDA receptor encephalitis (anti-NMDARE), we describe seizure phenotypes, electroencephalographic (EEG) findings, and anti-seizure treatment strategies. We also investigated whether specific electrographic features are associated with persistent seizures or status epilepticus after acute presentation. In this retrospective cohort study, we reviewed records of children and adults with anti-NMDARE between 2010 and 2014 who were included in the Rare Epilepsy of New York City database, which included the text of physician notes from five academic medical centers. Clinical history (e.g., seizure semiology) and EEG features (e.g., background organization, slowing, epileptiform activity, seizures, sleep architecture, extreme delta brush) were abstracted. We compared clinical features associated with persistent seizures (ongoing seizures after one month from presentation) and status epilepticus, using bivariate and multivariable analyses. Among the 38 individuals with definite anti-NMDARE, 32 (84%) had seizures and 29 (76%) had seizures captured on EEG. Electrographic-only seizures were identified in five (13%) individuals. Seizures started at a median of four days after initial symptoms (IQR: 3-6 days). Frontal lobe-onset focal seizures were most common (n=12; 32%). Most individuals (31/38; 82%) were refractory to anti-seizure medications. Status epilepticus was associated with younger age (15 years [9-20] vs. 23 years [18-27]; p=0.04) and Hispanic ethnicity (30 [80%] vs. 8 [36%]; p=0.04). Persistent seizures (ongoing seizures after one month from presentation) were associated with younger age (nine years [3-14] vs. 22 years [15-28]; p<0.01). Measured electrographic features were not associated with persistent seizures. Seizures associated with anti-NMDARE are primarily focal seizures originating in the frontal lobes. Younger patients may be at increased risk of epileptogenesis and status epilepticus. Continuous EEG monitoring helps identify subclinical seizures, but specific EEG findings may not predict the severity or persistence of seizures during hospitalization.

Rapid Diagnosis of Meningococcal Meningitis in a Patient With Familial Mediterranean Fever by the FilmArray Meningitis/Encephalitis Panel: A Case Report.

Familial Mediterranean fever (FMF) is a rare autoinflammatory disorder of the innate immune system. Patients with innate immune system defects are at a high risk of meningococcal disease, although it is unclear if patients with FMF also have increased susceptibility to invasive infection. Herein, we present a diagnostically challenging case of a male adolescent with a past medical history of FMF stabilized on colchicine who presented with some of the early clinical features of community-acquired bacterial meningitis. To our knowledge, this is the first case of meningococcal meningitis in a patient with FMF diagnosed with the FilmArray Meningitis/Encephalitis (ME) Panel. This case report demonstrates that rapid detection of Neisseria meningitidis by the ME Panel can aid in the early diagnosis and prompt treatment of patients with suspected meningitis and may be the only positive test in patients with early presentation and/or prior antimicrobial therapy.

Central nervous system (CNS) enterovirus infections: A single center retrospective study on clinical features, diagnostic studies, and outcome.

Enteroviruses (EV) are responsible for a large number of meningoencephalitis cases, especially in children. The objective of this study was to identify modes of diagnosis including the significance of respiratory and cerebrospinal fluid samples, associated clinical characteristics, inpatient management, and outcome of individuals with EV infections of the central nervous system (CNS). Electronic medical records of individuals with enterovirus infections of the CNS who presented to the Columbia University Irving Medical Center and Children's Hospital of New York between January 1, 2012 and December 31, 2017 were reviewed retrospectively for demographic, epidemiological, and clinical data. The median age overall was 1.7 months (interquartile range 14 years) and most (62.4%) were male. The majority of CNS infections presented as meningitis (95.7%) and occurred in the summer (45.2%) and fall seasons (37.6%). Eighty-five cases (91.4%) demonstrated EV positivity in cerebrospinal fluid, thirty cases (32.3%) exhibited both cerebrospinal fluid and respiratory positivity, and eight cases (8.6%) exhibited respiratory positivity with coinciding neurological findings. Eighty-nine individuals overall (95.7%) received antibiotics and 37 (39.8%) received antiviral treatment. All surviving individuals had favorable Modified Rankin Scores (MRS) within the zero to two ranges upon discharge. Testing respiratory samples in addition to cerebrospinal fluid was found to be an important diagnostic tool in EV-associated cases. While clinical outcomes were favorable for an overwhelming majority of cases, etiological understanding of CNS infections is essential for identifying ongoing and changing epidemiological patterns and aid in improving the diagnosis and treatment.

Screening for Both Child Behavior and Social Determinants of Health in Pediatric Primary Care.

OBJECTIVE: To implement comprehensive screening for child behavior and social determinants of health in an urban pediatric practice and explore rates of referrals and follow-up for positive screens. METHOD: Quality improvement methodology was used to implement routine screening using an adapted version of the Survey of Well Being of Young Children, a child behavior and social screen, for all children aged 6 months to 10 years. Rates of screen administration and documentation were assessed for 18 months. Medical records of a convenience sample (N = 349) were reviewed to track referrals and follow-up for positive screens. A secondary analysis explored associations between reported parental concern for their child's behavior and both child behavior symptoms and social stressors. RESULTS: Over 18 months, 2028 screens were administered. Screening rates reached 90% after introducing a tablet for screening. Provider documentation of screens averaged 62%. In the convenience sample, 28% scored positive for a behavioral problem, and 25% reported at least 1 social stressor. Of those with positive child behavior or social stressor screens, approximately 80% followed up with their primary medical doctor, and approximately 50% completed referrals to the clinic social worker. Further analysis indicated that referral and follow-up rates varied depending on whether the family identified child behavior or social issues. Logistic regression revealed that parental concern was independently associated with child behavior symptoms (p = 0.001) and social stressors (p = 0.002). CONCLUSION: Implementing a comprehensive psychosocial screen is feasible in pediatric primary care and may help target referrals to address psychosocial health needs.

Improving lipid control following myocardial infarction.

PURPOSE OF REVIEW: Following a myocardial infarction, lipid-lowering therapy is an established intervention to reduce the risk of recurrent cardiovascular events. Prior studies show a need to improve clinical practice in this area. Here, we review the latest research and perspectives on improving postmyocardial infarction lipid control. RECENT FINDINGS: Dyslipidemia and myocardial infarction remain leading causes of global disability and premature mortality throughout the world. The processes of care in lipid control involve multiple patient-level, provider-level, and healthcare system-level factors. They can be challenging to coordinate. Recent studies show suboptimal use of early high-intensity statin therapy and overall lipid control following myocardial infarction. Encouragingly, lipid control has improved over the last decade. Implementation science has identified checklists as an effective tool. At the top of the checklist for reducing atherogenic lipids and recurrent event risk postmyocardial infarction is early high-intensity statin therapy. Smoking cessation and participation in cardiac rehabilitation are also priorities, as are lifestyle counseling, promotion of medication adherence, ongoing lipid surveillance, and medication management. SUMMARY: Optimizing lipid control could further enhance clinical outcomes after myocardial infarction.
